Abstract
A device for the combined measurement of the arterial oxygen saturation and the transcutaneous CO2 partial pressure on an ear lobe comprises a sensor. The sensor has means for pulse oximetric measurement of the arterial oxygen saturation, means for measurement of the transcutaneous CO2 partial pressure and means for warming a sensor contact surface intended for contact with the ear lobe. The device makes simple and reliable measurement of the arterial oxygen saturation and the transcutaneous CO2 partial pressure possible on an ear lobe.
